[0039] In the present application, the air conditioner performs a refrigeration cycle of the indoor unit of the air conditioner by using a compressor, a condenser, an expansion valve and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The indoor heat exchanger can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the indoor unit of the air conditioner can adjust the temperature of the indoor space. The outdoor unit of the air conditioner indoor unit refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner indoor unit includes the indoor heat exchanger, and the expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger. When the indoor heat exchanger functions as a condenser, the air conditioner indoor unit functions as a heater in the heating mode, and when the indoor heat exchanger functions as an indoor heat exchanger, the air conditioner indoor unit functions as a cooler in the cooling mode.

[0040] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0041] As attached Figures 1 to 5As shown, in an exemplary embodiment of the indoor air conditioner of the present invention, the indoor air conditioner includes: a housing 100, an air guide plate 200, a driving member, an air conditioning fan, a fresh air fan and a controller, wherein the housing 100 is provided with an air outlet 300 and a fresh air outlet 400; the air guide plate 200 is arranged on the housing 100, and the air guide plate 200 is used to open and close the fresh air outlet 400; the driving member is used to drive the air guide plate 200 to flip; the air conditioning fan is arranged in the housing 100 and is used to output indoor air through the air outlet 300; the air conditioning fan has a first air conditioning speed, a second air conditioning speed and a third air conditioning speed, the speeds of which increase in sequence; the fresh air fan is provided with a It is placed in the shell 100 and is used to output outdoor air through the fresh air outlet 400; the controller is configured as follows: when the air-conditioning indoor unit is turned on and runs the fresh air mode, the fresh air fan runs at a preset speed, the air-conditioning fan runs at a first air-conditioning speed, and at the same time the controller controls the driving member to drive the air guide plate 200 to flip to open the fresh air outlet 400; the airflow passing through the air outlet 300 drives the airflow passing through the fresh air outlet 400 to blow into the room; during the flipping process of the air guide plate 200, the area of ​​the air guide plate 200 blocking the air outlet 300 and the fresh air outlet 400 gradually decreases, the speed of the air-conditioning fan is controlled to gradually increase, and the air volume passing through the fresh air outlet 400 gradually increases.

[0042] The air conditioning fan and the fresh air fan are operated simultaneously, the air conditioning fan outputs air through the air outlet 300 to form air conditioning wind; the fresh air fan outputs air through the fresh air outlet 400 to form indoor fresh air. Compared with the prior art in which fresh air is delivered only by a single fresh air fan, the air conditioning wind and fresh air in the present application are pulled together to increase the delivery distance of the fresh air.

[0043] Please refer to Figures 1 to 3 In some embodiments, the fresh air fan has a first fresh air speed, a second fresh air speed, and a third fresh air speed, the speeds of which increase in sequence. The preset speed of the fresh air fan is any one of the first fresh air speed, the second fresh air speed, and the third fresh air speed.

[0044] In some embodiments, after the air conditioner indoor unit is turned on and operates in fresh air mode, the fresh air fan operates at a first fresh air speed.

[0048] In some embodiments, after the air conditioner indoor unit is turned on and operates in fresh air mode, the air guide plate 200 starts to flip from a state of completely closing the fresh air outlet 400. When the air guide plate 200 flips to a half-open state, the angle between the air guide plate 200 and the housing 100 is half of the maximum flip angle of the air guide plate 200.

[0049] In some embodiments, the first preset time is 4 to 6 seconds. The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit connected to each other. After the air conditioner indoor unit is turned on and runs the fresh air mode, the air conditioner will detect the temperature of the external air within the first preset time. When the temperature is lower than the preset value or the temperature is higher than the preset value, the controller controls the fresh air fan to continue to run at the first fresh air speed or stops the fresh air fan. The first preset time is for the air conditioner to detect the external air temperature to ensure that the air conditioner can run accurately.

[0050] In some embodiments, the first preset time is 5S.

That is, after the air conditioner indoor unit is turned on and operates in the fresh air mode, the air guide plate 200 slowly turns over, and the speed of the air conditioner fan gradually increases. When the first preset time is reached, the air guide plate 200 is in a half-open state, and the speed of the air conditioner fan increases to the second air conditioner speed.

[0052] In some embodiments, after the air guide plate 200 reaches the half-open state, the air guide plate 200 continues to slowly flip to open the fresh air outlet 400, and the air conditioning fan continues to increase the speed. After the air guide plate 200 is fully opened, the air conditioning fan operates at a third air conditioning speed. The opening and closing range of the air guide plate 200 corresponds to the speed of the air conditioning fan.

[0053] In some embodiments, the air guide plate 200 has a uniform turning speed during the process of opening the fresh air outlet 400. The air conditioner fan has a uniform speed increase during the process of increasing from the first air conditioner speed to the third air conditioner speed.

[0055] In some embodiments, after the air conditioning fan runs at the third air conditioning speed and reaches a preset condition, the controller controls the driving member to drive the air guide plate 200 to slowly flip from a fully open state to a half-open state, and the speed of the air conditioning fan decreases. When the air guide plate 200 is in the half-open state, the air conditioning fan runs at the second air conditioning speed. The air guide plate 200 continues to flip and the speed of the air conditioning fan continues to decrease. When the air guide plate 200 completely closes the fresh air outlet 400, the air conditioning fan is in a closed state.

[0056] In some embodiments, after the air conditioning fan runs at the third air conditioning speed to meet a preset condition, when the air guide plate 200 is flipped to a half-open state, the air conditioning fan runs at the first air conditioning speed.
